摘要

硅锰渣是铁合金工业的副产物，对环境造成污染，消耗资源。在本研究中，作者探索了使用水玻璃浸泡来提高SS的性能，并将其用于生产超高性能混凝土(UHPC)。结果表明:水玻璃浓度为2%的SS处理24h后，复合材料的抗压强度比纯UHPC提高了16 MPa;此外，经冻融试验，处理后的复合材料的质量和抗压强度损失约为纯UHPC的一半，表明该处理对超高硅锰渣性能混凝土(UHPSSC)的抗冻融性能有显著的积极影响。微观结构分析还表明，水玻璃浸渍优化了UHPSSC的形貌，提高了复合材料的力学性能和抗冻融性能。

The optimized performance of ultra-high performance silicomanganese slag concrete by water glass immersion

Silicomanganese slag (SS) is a byproduct of the ferroalloy industry and cause environmental pollution and consume resources. In this study, the authors explored the use of water glass immersion to improve the performance of SS and used it to produce ultra-high performance concrete (UHPC). The results showed that SS treating with a 2% water glass concentration for 24 hours resulted 16 MPa higher compressive strength for composite than pure UHPC. Additionally, the treated composite had approximately half the mass and compressive strength losses of pure UHPC after freeze-thaw test, indicating that the treatment had a significant positive effect on the freeze-thaw resistance of ultra-high silicomanganese slag performance concrete (UHPSSC). Micro-structural analysis also showed that water glass immersion optimized the morphology of UHPSSC, contributing to improved mechanical performance and freeze-thaw resistance of the composite.

期刊介绍： For concrete and other cementitious derivatives to be developed further, we need to understand the use of alternative hydraulically active materials used in combination with plain Portland Cement, sustainability and durability issues. Both fundamental and best practice issues need to be addressed. Magazine of Concrete Research covers every aspect of concrete manufacture and behaviour from performance and evaluation of constituent materials to mix design, testing, durability, structural analysis and composite construction.
